The NEW TransChill Arctic Black Transmission Cooler Kit (TCB601DPK) is designed to suit Isuzu D-Max and MU-X models fitted with the 4JJ1-TCX 3.0L 4-cylinder engine (2012–2020). It is specifically engineered to reduce excessive transmission heat generated during towing, carrying heavy loads, off-road driving, and extreme conditions such as sand, snow, or high ambient temperatures.
The 32mm, 14-row TransChill transmission cooler provides an effective and economical solution for maintaining optimal transmission operating temperatures. High-efficiency turbulators within each tube enhance fluid flow for superior heat transfer, while the advanced plate-and-fin design delivers outstanding cooling performance. Its compact construction allows for seamless integration with vehicle-specific mounting systems.
Key Features:
- New and improved design
- Designed and engineered in Australia
- 32mm, 14-row plate-and-fin construction for maximum cooling efficiency
- Durable black powder-coated finish to resist oxidation
- Pressure tested to 150 psi for quality assurance and reliability
- Internal tubulation improves heat transfer performance
- Up to 50% greater efficiency (heat transfer rate – BTU/hr)
- Pre-drilled mounting plates for easy installation
- M16 inlet and outlet fittings
Why You Need One:
Automatic transmissions generate significant heat, especially under load. An auxiliary transmission cooler is a cost-effective way to help prevent expensive transmission damage. Automatic Transmission Fluid (ATF) plays a critical role in cooling, lubricating, and cleaning internal components. However, once temperatures exceed 93°C (200°F), ATF performance rapidly deteriorates.
Excessive heat can significantly reduce the lifespan of ATF, seals, and internal transmission components, while also increasing wear on friction materials and clutch plates.
How It Works:
The Direction-Plus™ Transmission Cooler Kit can reduce ATF temperatures by up to 33°C, helping maintain safe operating conditions. Even a reduction of just 11°C can potentially double the lifespan of the transmission, fluid, and internal components.
Kit Contents:
- Vehicle-specific laser-cut 4mm 5005-H34 aluminium mounting brackets
- Complete mounting hardware
- ATF hose (meets or exceeds SAE J1019 requirements)
- 1 x Davies Craig 32mm, 14-row black oil cooler
Backed by a 3-year warranty (conditions apply), this kit is a dependable upgrade for improved transmission performance, durability, and longevity.
